i want to go to a 520 chain. can u guys tell the pros and cons?
Big Daddy said:The DID 520erv2 is da best DID offers, it has a higher tensile strength & wear index than the VM series. I've used it many times on different bikes and it deffinately can withstand the rigours of street & track.
swjohnsey said:Most of the weight reduction from going with a 520 conversion comes from using a aluminum rear sprocket. The normal weight reduction is in the neighborhood of 2 pounds but it is rotating mass. If you only changed the rear sprocket and kept the 525 chain you would probably lose about 1 1/2 lbs. Now the 520 and 525 chains have about the same tensile strength and wear resistance. The thing that concerns me is that 520 sprockets are about 20% thinner which means that have about 20% less wear area.
Will a 520 hard anodized rear sprocket last as long as a quality chain. How about the front sprocket? It has been my experience that the front sprocket is the weak link.
8,250...............i might add that i did not convert to a 520 when changing my final drive setup but instead stayed with a 525 but used a AFAM hardened alum sprocket and Ti nutsbusaforhire said:what is the tensile strength of that chain..??
The front is not the weak link as it is a hardened chromemoly steel, hence far superior than say a hardened alum rear where the chain does have a tendency to bit a bit looser (if thats possible)swjohnsey said:How about the front sprocket?
